Abstract :
A computationally inexpensive algorithm for signal interpolation using B-spline functions is presented. Specifically, the convolution between the B-spline coefficients and the B-spline function itself, widely acknowledged as the most costly aspect of B-spline interpolation, is reformulated such that it is directly amenable to implementation at a much lower computational cost (16.25% of the cost of direct evaluation)
